Aster develops and manufactures ASTERCOIL aluminium-winding motors and power units for compact, high-output electromechanical systems.
About
Aster is a Japanese motor and power-unit manufacturer based in Yokote, Akita. Its proprietary ASTERCOIL technology uses shaped aluminium windings to combine compact size, low mass and high output in next-generation electric motors.
A 2026 capital and business alliance with Akari funds production equipment and hiring while adding digital-twin and Physical AI tools to Aster’s factory. The partners plan to feed operating data back into motor production and extend the resulting systems toward hybrid drones, generators and future humanoid applications.
